This invention relates to new and useful improvements in mattresses.

More specifically, the present invention proposes the construction of animproved mattress for home use in connection with a conventional bed andspring and. which is provided with means for raising the head end and/orthe foot end in a manner to meet the needs of the occupant or occupantsof the bed.

Still further, the present invention proposes characterizing themattress by superimposed suitably padded upper and lower mattress layersbetween which a substantially co-extensive rigid plate is interposed andwhich is provided with the means for raising the head end and/or thefoot end of the upper of the mattress layers to suitably support thebodies of the occupant or occupants of the bed.

The present invention is further characterized by the fact that aheadboard is `pivotally mounted on the rigid plate beneath the head endof the upper mattress layer and which is resiliently urged to aninclined position in a manner to raise the head end of the uppermattress layer i to support the head and shoulders of the occu- 'f pantor occupants of the bed for reading or the like.

As a further object, the present invention proposes providing the rigidboard adjacent the foot end thereof with means for raising the foot endfof the upper mattress layer in a manner to support the legs and feet ofthe occupant or cocu pants of the bed in an elevated position.

Still further, the present invention proposes constructing the means forraising the foot end headboard to raise the head end of theuppermattress layer and/or for releasing the means for raising the uppermattress layer at the foot end thereof.

Still further, the present invention proposes constructing themattresses forms characterized by different means for raising the uppermattress layer at the foot end thereof.

It is a further object of the present invention to construct mattressesof the type disclosedy in two different .2 Y which are simple anddurable, which are effective for their intended purposes and which canbe manufactured and'sold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

detailed view of a por- The mattress, according to the first form of thepresent invention, shown in Figs. 1 to l2, includes an upper mattresslayer 26 and a lower mattress layer 2|. The mattress layers 26 and 2|are coextensive with the upper layer 26 superimposed on the lower layer2|. Each of the mattress layers 23 and 2| is alike in constructionhaving an outer tick 22 enclosing the usual padding material 23 whichmay or may not include inner springs as desired. A joining strip 24,formed of the same material as the outer tick 22 of the mattress layers,is engaged about the periphery of the layers and joined thereto by theusual stitches 25 extended about the peripheryy of the mattress layers,see Figs. 6 and 7. The joining strip 24 functions to hold the uppermattress layer 26 superimposed on the lower mattress layer 2l.

A rigid plate 2B is inserted in position between the adjacent faces ofthe mattress layers 26 and 2|. The rigid plate 26 may, if desired, besecured to the lower mattress layerv 2|l to prevent shifting of theplate 26 relative to the. layers 23 and 2|. However, frictional contactbetween the plate 26 and the mattress layers is deemed sufficient toretain the plate 26 i'lxedly in place be tween the mattress layers. 26and` 2|. Ther plate 26 is preferably formed of a lightweight materialsuch as wood, one of the lightweight non-cor" rosive metals or asynthetic resinous material.

The plate 26, at the head end o1" the mattress, is formed with anundercut top tace forming a space in which a headboard 21 is located,see Figs. 4, 5, and 11. At its edge nearer the foot of the bed,headboard 2-1 is pivotally attached to the plate 26 by meansof hinges28.

The hinges 28 have one of their' leaves secured to the plate 26 andtheir other leaves secured to the headboard 21,. The headboard 21 isformed of the same material as the plate 26. Elongated leaf springs 29are located between the adjacent faces of the rigid platev 26 and thehead board 21 and along the outerI edges of the. headboard. The leafsprings 2.3i each have. one end secured to the plate 2-6 by means ofrivets 30. The attached ends` of the leaf; springs 29 are locatedadjacent the pivoted edge of the headboard 21. The free. ends of theleaf. springs 29 engage the bottom face of the headboard 21 and urge itinto an upwardly inclined position supporting the head end of thev uppermattress layer 26 in the inclined position `shown in Figs- 3` and 5 tosimilarly support thel head' and shoulders of the occupant or occupantsof the bed provided with the mattress. The joining strip 2'4 at the headend of the mattress is provided with a pleated area 2f.a which expandswhen the head end of the upper mattress layer 20 is raised by theheadboard 2-1. The pleated area 24a can be integrally formed with thejoining strip 24 or may be a separate piece of pleated material set intoa slit formed inthe joining strip 24', so as to expand when the head endof the upper mattress layer 20 is raised.

Electrically controlled means is provided for holding the headboard in alowered position against the normal action of the leaf springs 29. Theelectrically controlled means is characterized by a single solenoid 3|xedly mounted in a recess 32 formed in the plate 26 midway of itslongitudinal side edges. The solenoid 3| is located below the free edgeof the headboard 21. The solenoid 3| has a metallic. core S3 arranged toslide parallel to the length of the plate 23 and provided at its freeinner end withl a beveled end 4 34 for engagement with a complementarybracket 35 secured to the bottom face of the headboard 21.

As best shown in Fig. l0, the bracket 35 has a depending portion formedwith an opening 36 into which the beveled end 34 of the core 33 extendsto hold the headboard 21 in the lowered position.

Adjacent its beveled end 34, the core 33 is formed with an enlarged ange31 and is sleeved by a coil spring 33. The coil spring 38 operatesbetween the flange 31 and the adjacent end of the solenoid 3| to holdthe beveled end of the core 33 in engagement with the opening 36 of thebracket 35. The end of the core 33 remote from the beveled end 34, isformed with an enlarged headV 33 to hold the core from being completelypulledY out` of the solenoid 3| by the action of the spring 38.Normally, the core 33 functions to hold the headboard 21 in the loweredposition shown in Figs. 1, 2, 4 and 10. Circuit means, to be hereinafterdescribed, are provided for moving the core 33 against the action of thespring 38 to move its beveled end 34 out of the opening 36..Immediately, the springs 23 function to pivot the headboard 21 upward toraise the head end of the upper mattress layer 23 to the raised positionshown in Figs. 3 and 5. To again lower the headboard 21 and the head endof the upper mattress layer 2! they must be manually pushed down untilthe beveled end of the core 33 snaps into the opening 33v of the bracket35.

Means is provided for raising the foot end of the upper mattress layer23 to similarly raise the legs and thighs of the occupant or occupantsof the bed equipped with the mattress. The raising means for the footend of the upper mattress layer 26 is characterized by a flat platform40, see Figs. 4 to '7, superimposed above a thickened foot end portion26a of the rigid plate 2S. Depending from the bottom face ofV theplatform 46, at the four corners thereof, there are vertical posts 4|.

The posts 4| are depended slidably through complementary holes 42 and 43formed in the plate 26 and the foot end of the bottom mattress layer 2|,see particularly Fig. 9. The hole 43 of the bottom mattress layer 2! isreinforced by tubes of cloth material stitched at their top and bottomends to the tick 22 of the lower mattress layer 2|. In the loweredposition of the platform 40, the posts 4| depend from the bottom face ofthe lower mattress layer 2| and through the openings of the spring ofthe bed upon which the mattress rests. If the bed is equipped with aboxspring, it must be formed with suitable openings to accommodate thedepending ends of the posts 4|.

The outer longitudinal edges of the rigid plate 26 is formed withcutouts 4J! in which pairs of arms 45 are located. The outer ends of thearms 45 are pivotally supported on trunnions it@ which extend from thematerial of the plate into the cutouts lit. The free ends of the arms @5are formed with rollers 41 for rolling on the bottom face o the platformd0. Stiff springs 48 are positioned within the cutouts 43 beneath eachof the arms t5. Each of the springs iihas one end secured by rivets 39to the material of the plate 26 at the base of the cutouts 44. The otherends of the spring 438 bear against the bottom edges of the arms @5urging the arms 35 into the upwardly inclined positions shown in Figs.3, 5 and '7, raising the platform and the foot end of the upper mattresslayer 23 horizontally. As in the case ofthe head end of the mattress,the

joining strip 24 at the foot end is formed with a pleated area 24b whichpermits the upward raising of the platform 40 and the foot end of theupper mattress layer 26. Such upward movement is arrested by completeexpansion of the pleated area 24b of the joining strip 24.

Electrically controlled means is provided for holding the platform 46 inthe lowered position shown in Figs. l, 2, 4 and 6 against the action ofthe springs 48 on the bottom edges of the arms 45. That means comprisesa solenoid 49 mounted on the top face of the plate 26 immediatelyadjacent the posts 4l at opposite corners of the platform 46. Thesolenoids 49 have cores 56 arranged to slide toward and away from therespective posts 4I. Springs 5I operate between pins 52 extended upwardfrom the solenoids 49 and pins 53 extended upward from the ends of thecores 59 remote from the posts 4I. The springs 5I act in contraction andurge the cores 56 into contact with the respective posts 4I to extendinto complementary niches 54 formed in the sides of the posts 4I to holdthe platform 4B in the lowered position shown in Figs. 4 and 6. Circuitmeans to be hereinafter described, is provided for energizing thesolenoids 49 to withdraw the cores 56 from the niches 54 against theaction of the springs 5|. That functions to free the platform 49 to beraised by the action of the springs 48 on the arms 45. To again lowerthe platform, the foot end of the upper mattress layer 20 must bemanually pressed downward until the cores 50 snap into niches 54.

Support means is provided for that portion of the upper mattress layer20 Where it slopes downward from the platform 40 in the raised positionthereof. The support means is characterized by a base member 55supported to slide longitudinally on the top face of the fixed plate 26.Superimposed on the base member, there is a topv member 56 pivoted tothe base member 55 by means of hinges 51. Leaf springs 58 are secured tothe bottom face of the top member 56 at its edge remote from the hinges'51 by means of rivets 59.

The free ends of the leaf spring 58 bear against the top face of thebase member 55 urging the top member 56 into the inclined position shownin Figs. 5 and '1.

Secured to the bottom face of the base member 55, there is a pair oflaterally spaced longitudinally extending racks 60. The racks 66 slidein parallel longitudinally extending grooves 6I formed in the top faceof the plate 26. Between the grooves 6! the thickened foot portion 26aof the plate 26 is formed with a hollow 62 in which electricallycontrolled means is provided for moving the base member 55 back andforth relative to the platform 40. The electrically controlled means ischaracterized by end aligned opposed solenoids 63 and 64 between which asingle core 65 is slidably extended. When the solenoid 63 is energized,the core 65 is moved away from the foot end of the mattress and when thesolenoid 64 is energized, the core 65 is moved toward the foot end ofthe mattress. The circuits for controlling the energization of thesolenoids 63 and 64 will be hereinafter described.

The bottom face of the core 65 is formed with rack teeth 66 which meshwith a small pinion 61 fixed to the shaft 6B rotatively supportedbetween the side walls of the hollow 62. Fixed on the shaft 68 to oneside of the pinion 61, there is .a larger pinion 69 which in turn mesheswith a smaller pinion 10 mounted on a second shaft 1| rotativelyextended between the opposed walls of the hollow 62. The pinion 10 inturn drives another small pinion 12 fixed to a shaft 13 which has itsends extended beyond the racks 66 and rotatively supported on theopposed side walls: of the hollow 62. Beneath each of the racks 6l)y theshaft 13 carries a large gear 14 which meshes with the racks 60. Thegears 14 are both of the same size.

y The gear train interposed between the core 65 and the racks 66provides the solenoids 63 and 64 with a mechanical advantage for movingthe base member 55 and its pivotally mounted top member 56 back andforth relative to the platform 40.

In the lowered position of the platform v4l), the top member 56 is heldlowered onto the base member 55 against the action of the leaf springs58 by the same means which holds the platform 46 lowered. When theplatform 40 is free to be raised by the action of the springs 48' on thearms 45, the springs 56 are also freed to raise the top member 56relative to the base member 55. In the completely raised position of theplatform 46, the solenoid 63 is then energized to move the base member55 and the top member 56 from beneath the platform 46 and into positionbeneath the downwardly inclined portion of the upper mattress layer 26,as shown in Figs. 5 and 1. 'Ifo move the base member 55 and the topmember 56 back into position beneath the platform 49, the solenoid 64 isenergized. When in position beneath the platform 46 pressures applied tothe top mattress layer 26 to lower the platform against the action ofthe spring 48 will also lower the top member 56 against the action ofthe springs 58.

The electrical circuits for controlling the solenoids 3 I, 49, 63 and 64are shown in the schematic wiring diagram of Fig. l2. Those circuits areoperated from a single control box 15 separate from the mattress to bepositioned on a night table or the like within convenient reach of theoccupant or occupants of the bed. The control box 15 has one push button16 for energizing the solenoid 3 I, another push button 11 forenergizing the solenoid 63, another push button 18 for energizing thesolenoid 64 and a last push button 19 `for energizing the solenoids 49in unison.

Extending from the control box 15 there is a lead-in wire 60 provided atits free end with a plug 8l for insertion into a conventional outletreceptacle for supplying the required electric current. The Wireincludes the usual parallel leads 82 and 83. Each of the push buttons16, 11, 18 and 19 has a pair of contacts and within the control box 15,the lead 83 has branches connected to one contact of each of thepush-buttons. The lead 82 extends through the control box and out againinto the mattress where it is sub-divided into five branches 82, 82h,82, 82d and 82e. The branch 62a goes to one side of the solenoid 3l. Thebranch 82b is connected to one side of the solenoid 63 and one side ofthe branch 62c is connected to one side of thel solenoid 64. Thebranches 82d and 82e are connected respectively to one side of thesolenoids 49.

vExtended from the other contact of the push button 16, there is a lead84 which is connected to the other side of the solenoid 3| so that whenthe push button 116 is pushed inward the solenoid 3| is energized tofree the headboard 21. A lead 85 extends from the other contact of thepush button 11 and is connected to the other side of the solenoid 63 forenergizing that solenoid when the push button 11 is pressed inward tomove the ense-,595

Abase member 55 and its top member 56 outfrom beneath the platform .49.A lead 86 extends-from the other contact of lthe push button 18 and `isconnected -to the other side of the solenoid 64 for energizingthatsolenoid when the push button 18 is pressed inward to move the basemember 155 and its top member 5t back into position :beneath theplatform. Extending from the other contact of the push button 79 thereis a lead 81. rIhe lead 8l is extended into `the mattress 'and dividedinto branches connected to the other 'side of each of the solenoids 49.

Thus, .when the push Vbutton i9 is pushed inward, the two solenoids 49will be energized to .withdraw vtheir respective cores 50 to free the:platform 4i! to be raised by the action vof the `springs i8 on the arms.45.

The leads 52, `81|, 85, 86 and 81 where they extend between the controlbox 'l5 and the mattress are embodied in a single cable 88.

.The modification of the invention shown in Figs. 13 Vto lediffers fromthe previous form in the construction .of the means associated with thefixed plate 2B' for raising the foot end of the upper mattress layer 2D.The head endof the plate is provided with the same pivotally mountedheadboard 2l for raising the head end of the upper mattress layer 29.

As in the previous form of the invention, the fixed rigid plate 2-5'isformed adjacent the foot vend thereof with a thickened portion 26bhaving a hollow 90. -Posiitoned within the hollow 99, Vthere is aU-shaped member 9| having spaced side arms 92 positioned nat against theside walls of the hollow 99. The free ends of the side arms 92 arepivoted to the opposed side walls of the hollow 99 by end aligned pins93 so that the U-shaped member 9| can pivot in and out of the hollow 99.The opposite -ends of the side arms 92 are joined by an integralintermediate arm which forms a platform 94 which is fixed relative tothe side arms 92. Extended transversely between the side arms 92 inwardof the platform y91S, there is a group of platforms 95. At their ends,the platforms 95 are provided with depending lugs pivotally attached tothe inner faces of the side arms 92 by means of pivot pins 95 so thatthe platforms 95 can pivot relative to the .side.arms-.92. .Elongatedleaf springs 91 are posi- .tioned within the hollow beneath each of theside arms 92 of the .IJ-shaped member 9|.

The leaf springs 9i have one of their endsattached to the bottomwall ofthe hollow by means vof rivets .9%. The free ends of the leaf springs.91 bear againstthe bottom edges of the side arms S2 to urge theU-shaped member 9| out of the .hollow 99 into the inclined positionshown in Fig. 14. When the Ushaped member 9| `is in the inclinedposition, the free edges Yof the .platforms -95 rest on pins 99 extendedinward from the -inner faces of the side arms .92 of the U- shapedmember. In the lowered position of the 1U-shapedmemberi, the free edgesof the .platforms 95 are held from pivoting upward .by ledge members v|iicarriedby the free edges of the two platforms remote from the xedplatform 94. 'In the vraised Vposition of the U-shaped member .9|, theplatforms 94 and-95 assume the stepped formation shown `in Fig. 14 tosupport .the foot Iend portion vof the upper mattress layer 20, tosimilarly support the legs andhips of the occupant or occupants of thebed provided with the mattress. Thesides of the joining strip .24', at

l.the sides-of the mattress aligned with the hollow `9|) of :thegrigid:plate 26 `is 'formed withvpleated `the core |03 has an enlarged flange|55.

areas 24 -which permit the raising of the .foot .end portion of theupper mattress layer 20. Up- -ward movement of the side arms Y92 of the.U-

shaped member 9|, under the influence `of the springs 9i, is arrestedupon complete extension of the pleated areas 24C.

Electrically controlled means is provided for holding the U-shapedmember 9| in a lowered position shown in Fig. 13 against the action ofthe springs 91. The holding means is best illustrated in Fig. l5, andincludes a solenoid IUI fixedly mounted within a recess il2 in the rigidplate 26 which opens into .the hollow 9.0 midway of the longitudinalsides of the rigid plate 26'. The solenoid |9| supports a core v|03forsliding `movement toward and away fromv the platform vtil.

The core |93 has an upwardly faced beveled end |64 for engaging the topface of the platform 94, as shown in Figs. i3 and 15, to hold the U-shaped member 9| lowered vagainst the action of the leaf springs 9i.Adjacent its'beveled end, A coil spring |539 .is wound'about the core|93 and operates between the ange 95 and the adjacent end of the core 63for urging the core into its extended position in which the beveled endl|04 engages the top face of the platform 94. The end of the core |93remote from the beveled end |94 has an enlarged head |01 for holding thecore |93 from being shot out of the solenoid mi by the spring |95.

Normally, the spring |95 holds the core' |03 extended, as shown in Figs.13 and 15, to engage the top face of the fixed platform 9d to hold theU-shaped member 9| lowered against the action of the spring |55. Thesolenoid |9| can be energized by circuit means to Vbe presentlydescribed, To withdraw the core ita against the action of the spring.|59 to free the U-shaped member 9| to be lraised by the springs 91 tothe position shownin Fig. 1.4 in which the foot end portion of the uppermattress layer 29 will be raised. To relower the foot end portion of theupper mattress layer 29, the same is manually pressed downward pivotingthe U-shaped member 9| into the hollow 99 against the action of thesprings 97. The outer edge of the xed platform @d will snap past thebeveled end |95 of the core |93 to again maintain the U-shaped member 9|in its lowered position until the solenoid lili is again energized.

The energizing circuit for the form of the invention illustrated inEigs. 13 to 16 is shown vin conjunction with Fig. i3. The circuitincludes a master control box 15 having a push button 15 and a secondpush button |68.

As in the previous form of the invention, each of the push buttons 75and |68 has a pair of contacts. The electric wire 8f3' extendingfrom theplug 8| to the control box l5 includes the leads 82 and 83. Within thecontrol boX 15, the lead 83 has branches connected to one of thecontacts of each of the push buttons VM5 and i-. The lead 32 extendsthrough the control box l5 into the mattress where it has separatebranches 82X and 825'. rihe lead 82X is connected to one side of thesolenoid 3| which controls the The lead 82Y is connected to one side ofthe solenoid 0|. A lead 84 extends from the other side of the pushbutton 'it to the other side of the solenoid 3| so that when the pushbutton 'I6 is pressed inward, the solenoid 3| will `be energized to freethe headboard 2l to be pivoted upward. Likewise, a lead |09 extends fromthe other Contact acreage 9 of the push button |08 to the other side ofthe solenoid ll to cause the solenoid lill to be energized to releasethe U-shaped member 9| to pivot upward when the push button |08 ispressed inward.

The leads 82', 84 and H39, where they extend from the control box l tothe mattress, are embodied in a single cab-le H0, just as in the rstform of the invention.

Rested on the top face of the mattress at opposite sides of the foot endthereof, there are pillows As best shown in Fig. 16, the pillows I|| areof truncated triangular shape. The pillows are provided to function asguides for indicating when the occupant or occupants of the bed equippedwith the mattress, have their legs located directly in the center of themattress.

In all other respects, the form of the invention illustrated in Figs. 13to 16 is similar to the first form and like reference numerals are usedto identify like parts of the invention.

From the foregoing description, it is apparent that the mattresses ofthe present invention provide convenient means for raising either orboth the head end or the foot end of the mattresses to similarly supportthe head and shoulders or the legs and hips of the occupant or occupantsof the bed equipped with the mattresses. The mechanisms employed forholding the parts of the mattresses in their raised positions areresilient in their formation so that the mattresses are not rigidlysupported in their raised positions but rather have certain amount ofplay to conform themselves to the particular needs of the occupant oroccupants of the bed.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asset forth in the appended claims.

Having thus 'described my invention, what I claim as new and desire tosecure Iby United States Letters Patent is:
